Decay properties of new D-mesons | | Ya. I. Azimov

8 Mar 2004 | | Journal: | Eur.Phys.J. A21 (2004) 501-506 | | Subject: | hep-ph | | Abstract: | We consider radiative and pionic decays of the new D_s-mesons in the framework of a phenomenologically motivated approach. Present data on ratios of the two kinds of decays can be described without explicit using a 4-quark component. Most probably, the isospin violation in decays of different D_s-mesons is not universal, and the binding potential should be different from Coulombic. New precise measurements may provide further clarification for the nature of the D_s excited states. | | Source: | arXiv, hep-ph/0403082 | | Services: | Forum | Review | PDF | Favorites | |
